This PR removes the keyword "Music" from Clapper's `.desktop` file to lower its priority as a music player in desktop search results. This ensures that Clapper is not prominently suggested when searching for music-related applications, while retaining its functionality as a video player.
### Changes:
- Removed "Music" from the `Keywords` field in the `.desktop` file.
This change does not affect Clapper's ability to play audio files but adjusts its visibility in application search results.
